Hi core-el,
First of all, Thank you very much for your replies.
Now i just want to make sure about the following:
I do a customization preference on Firefox 10.0.12 and packaging it to msi file (i do it by adding some files firefox.cfg etc...) and when installed it on any PC the Firefox installed successfully with all new preference, then i set "app.update.url" preference to my local installed Apache server (http://localhost/%PRODUCT%/%VERSION%/%LOCALE%/update.xml ).
update.xml file contains the update to version 12.
then chose "check for updates" from "Help" menu and i get the updated version of firefox with all customized preference.
this mean that Upgrading Firefox will replace its files, but it will not remove the manually added files.
So that there is no needs to customized the MAR file.
i tried this and its work fine for me. please confirm that , thank you very much again, waiting your response :)
